Electrochemical Studies on the Nickel-Catalyzed O−C(allyl) Bond Cleavage of Allyl Ethers
摘要:
The chemoselective electrochemical cleavage of allyl aryl ethers catalyzed by Ni(bipy)(3)(2+)2BF(4)(-) was shown to proceed through electrogenerated Ni(0) complexes with the formation of pi-allyl Ni(II) species, which are in turn reduced at the same potential as the initial Ni(II)/Ni(0) reduction. The important role of magnesium ions in the recycling of the nickel species was established.
